Description

Существующие способы обработки кордных нитей, включающие их выт гивание и свободную усадку, не обеспечивают надлежащей эластичности нитей.Existing methods for treating cord threads, including their stretching and free shrinkage, do not provide proper elasticity of the threads.

Предлагаемый способ позвол ет повысить эластичность за счет многократной (не менее трехступенчатой) выт жки нитей чередующейс  с их свободной усадкой. Кроме того, выт гивание провод т убывающими нагрузками, начина  с 70-75% от разрывной нагрузки в первой зоне и конча  10-IS/o в последней зоне выт гивани .The proposed method allows to increase the elasticity due to multiple (at least three-step) stretching of the threads alternating with their free shrinkage. In addition, the stretching is carried out with decreasing loads, starting from 70-75% of the breaking load in the first zone and ending with 10-IS / o in the last stretching zone.

Дл  облегчени  процесса выт гивани  и усадки может быть применена предварительна  пропитка и отжи.м нити.To facilitate the stretching and shrinking process, pre-impregnation and annealing of the yarn can be applied.

Процесс обработки кордных нитей по предлагаемому способу прот (-кает следующим образом.The process of processing cord yarns according to the proposed method of prot ((as follows).

Нить / (см. схему выт жки) с катушки 2 после 2-го кручени  прОходит поверхностную пропитку в ванне 3 и отжим. Затем она поступает на первую пару выт жных роликов 4 с канавками. Выт жка на этой паре максимальна -11% и соответствует отпосительно1му удлинению корда при раст жении его нагрузкой, равной 70-75% от разрывной. Далее нить поступает на вюрую пару вь1 1 жных роликов 5, где подвергаетс  (выт жке Пор дка 5% с нагрузкой корда 40-50% от разрывной.The thread / (see the drawing scheme) from the coil 2 after the 2nd torsion passes the surface impregnation in the bath 3 and the spinning. Then it enters the first pair of grooved exhaust rollers 4. Stretching on this pair is maximum -11% and corresponds to a relative elongation of the cord when it is stretched with a load equal to 70-75% of the breaking strength. Next, the thread enters a vural pair of curved rollers 5, where it is subjected (Approximately 5% stretching with a cord load of 40-50% of the breaking.

На последней паре выт жных роликов 6 нить выт гиваетс  нагрузкой , соответствующей 10-150/0 от разрывной. Получивща  (благодар  такой обработке) хорощуЮ эластичность нить, наматываетс  на катушку или сновальный вал. Повыщение эластичности кордных нитей при обработке их по предлагаемому способу подтверждено экспериментальными данными. Способ основан на использовании периодических релакс ций нити в процессе ее выт гивани .On the last pair of stretch rollers 6, the thread is pulled with a load corresponding to 10-150 / 0 from the breaking. Having obtained (thanks to such processing) the good elasticity of the thread, it is wound on a reel or a warp shaft. The increase in the elasticity of cord yarns in the processing of the proposed method is confirmed by experimental data. The method is based on the use of periodic relaxations of the thread in the process of its drawing.
